Russia says its ‘doomsday plane’ can now communicate with its deep sea nuclear submarines

Posted by in categories: existential risks, military

The test strengthens Russia’s nuclear command and control systems amid rising tensions with the West.

Russian defense officials are claiming a successful test of the Ilyushin Il-80 deep-sea communication system, allowing the Russian ‘Doomsday’ plane to communicate with deep-sea nuclear submarines in the event of a nuclear war.

According to the Russian state-owned news agency RIA Novosti, the Il-80 ‘Flying Kremlin’ successfully communicated with Russian nuclear submarines located deep underwater using ultra-long wave signals, enabling the Russian President to communicate and coordinate Russian military activity in the event of nuclear conflict.

Russia, U.S. to hold first talks under nuclear treaty since Ukraine war —State Dept

Posted by in categories: cybercrime/malcode, existential risks, geopolitics, military, nuclear energy, space travel, treaties

WASHINGTON, Nov 8 (Reuters) — The United States and Russia are expected to meet soon and discuss resuming inspections under the New START nuclear arms reduction treaty that have been paused since before Russia’s invasion of Ukraine, U.S. State Department spokesperson Ned Price said on Tuesday.

Speaking at a daily press briefing, Price said the bilateral consultative commission (BCC), the mechanism for implementation of the last remaining arms control agreement between the world’s two largest nuclear powers, will meet “in the near future.”

Russia in August suspended cooperation with inspections under the treaty, blaming travel restrictions imposed by Washington and its allies over Moscow’s February invasion of Ukraine, but said it was still committed to complying with the provisions of the treaty.

Even a small nuclear war could cause global famine — here’s what the data shows

Posted by in categories: climatology, computing, existential risks, geopolitics, military, nuclear weapons, treaties

Nuclear arsenals remain large enough to fundamentally shift the Earth system in the blink of an eye.

The U.S. and Russia have recently agreed to hold talks on the New START Treaty, and the only accord left regulating the two largest nuclear arsenals in the world. While this is undoubtedly good news, we must not allow it to lull us into complacency. Global events this year, most notably in Ukraine, have raised fears of a nuclear conflict to levels not seen since the cold war. More than 10,000 nuclear warheads remain in the world, and the Kremlin’s language regarding weapons of mass destruction has become increasingly threatening in 2022.

Ancient global ocean on Mars may have come from carbon-rich chondrite meteorites from the outer solar system

Posted by in categories: asteroid/comet impacts, existential risks

A team of researchers at the University of Copenhagen’s Center for Star and Planet Formation, working with colleagues from Université de Paris, ETH Zürich and the University of Bern, has found evidence suggesting that most of the water that made up an ancient global ocean on Mars came from carbon-rich chondrite meteorites from the outer solar system. The study is published in Science Advances.

Prior research has suggested that at one time, Mars was either mostly or entirely covered by a watery , and that the water came from gases seeping from below the surface and liquifying as they cooled. In this new effort, the researchers suggest the water more likely came from another source—meteorites traveling from the outer solar system.

The researchers came to this conclusion after studying fragments flung from the surface of Mars after asteroid strikes, which made their way to Earth as meteorites. The researchers studied 31 of them, looking most specifically for chromium isotopic fingerprints. Chromium-54 does not occur naturally on Mars; thus, its presence in crust samples from Mars would indicate that the surface had been struck by material from somewhere else.

Is Physical Law an Alien Intelligence?

Posted by in categories: alien life, existential risks, mobile phones, particle physics, singularity

Perhaps Arthur C. Clarke was being uncharacteristically unambitious. He once pointed out that any sufficiently advanced technology is going to be indistinguishable from magic. If you dropped in on a bunch of Paleolithic farmers with your iPhone and a pair of sneakers, you’d undoubtedly seem pretty magical. But the contrast is only middling: The farmers would still recognize you as basically like them, and before long they’d be taking selfies. But what if life has moved so far on that it doesn’t just appear magical, but appears like physics?

After all, if the cosmos holds other life, and if some of that life has evolved beyond our own waypoints of complexity and technology, we should be considering some very extreme possibilities. Today’s futurists and believers in a machine “singularity” predict that life and its technological baggage might end up so beyond our ken that we wouldn’t even realize we were staring at it. That’s quite a claim, yet it would neatly explain why we have yet to see advanced intelligence in the cosmos around us, despite the sheer number of planets it could have arisen on—the so-called Fermi Paradox.

For example, if machines continue to grow exponentially in speed and sophistication, they will one day be able to decode the staggering complexity of the living world, from its atoms and molecules all the way up to entire planetary biomes. Presumably life doesn’t have to be made of atoms and molecules, but could be assembled from any set of building blocks with the requisite complexity. If so, a civilization could then transcribe itself and its entire physical realm into new forms. Indeed, perhaps our universe is one of the new forms into which some other civilization transcribed its world.

Fermi Paradox: Stay At Home Civilizations

Posted by in categories: existential risks, space travel

Today we return to the Fermi Paradox to contemplate the notion of civilizations which neither expand outwards to colonize the galaxy nor go extinct, but exist as long-term, high-tech civilizations just on their own planet or solar system. To discuss the possible motives and reasoning we will look at the many arguments raised for and against space exploration.

Mars shows how even the simplest life forms can destroy their own planet

Posted by in categories: asteroid/comet impacts, climatology, evolution, existential risks

Microbial life may have resided within the first four kilometers of Mars’s porous crust.

Four billion years ago, the solar system was still young. Almost fully formed, its planets were starting to experience asteroid strikes a little less frequently. Our own planet could have become habitable as long as 3.9 billion years ago, but its primitive biosphere was much different than it is today. Life had not yet invented photosynthesis, which some 500 million years later would become its main source of energy. The primordial microbes — the common ancestors to all current life forms on Earth — in our planet’s oceans, therefore, had to survive on another source of energy.


Some of the oldest life forms in our biosphere were microorganisms known as “hydrogenotrophic methanogens” that particularly benefited from the atmospheric composition of the time. Feeding on the CO2 (carbon dioxide) and H2 (dihydrogen) that abounded in the atmosphere (with H2 representing between 0.01 and 0.1% of the atmospheric composition, compared to the current approximate of 0.00005%), they harnessed enough energy to colonize the surface of our planet’s oceans.

10 Paradoxes That Will Stretch Your Mind

Posted by in categories: alien life, existential risks, physics

As in physics, paradoxes in biology really are just unsolved puzzles. Enter Peto’s paradox. Biologist Richard Peto noticed in the 1970s that mice had a much higher rate of cancer than humans do, which doesn’t make any sense. Humans have over 1,000 times as many cells as mice, and cancer is simply a rogue cell that goes on multiplying out of control. One would expect humans to be more likely to get cancer than smaller creatures such as mice. This paradox occurs across all species, too: blue whales are much less likely to get cancer than humans, even though they have many more cells in their bodies.
